Sagal, who was prepping for an appearance by White House spokesman Tony Snow, said he has not settled on Breyer's three questions. But the host said he is curious about how the justices get along, among other things.

"How do you decide what to order for lunch when having a working lunch at the Supreme Court? Does the chief justice say, 'Let's see, there are four votes for Chinese food?" Sagal said.

Breyer, apparently a fan of radio quiz shows during his youth, was volunteered for the program by his brother, Charles, also a federal judge.
